Abstract
Oral care compositions and methods are described in which the composition includes a chalcone color change component, which may be phenyl-3-methoxy-4-hydroxystyryl ketone. The color change component is induced to change colors by addition of saliva and/or by a change in pH of the composition. The composition and methods provide benefits including providing visual cues to the user.
